along the shaft 5 and aidi in'holding the arms ltl, 16 and 18 against swinging too freely, the function of the spring 7 and the wing nut SOof Figure 3 being recalled at this point.

Passing to a specific description of the means for mounting the earth globe 44 on the arm 18, it is to be observed, referring to Figure 3, that a c0upling 3'2 is carried by the outer end of the arm, an outstanding shaft'33 being mounted in the coupling, nuts 34 bein threaded uponthe shaft and being enga with the coupling. A hub 35 is rotatab y adjustable on the shaft 33, and carries an angular arm 36, the outstanding por tionof which is supplied with an index 37, shown in Figure 4,'t eindex being secured at 38 to the outstanding portion of the arm 36, as depicted in Figure 5. The outstanding portion of the arm 36 carries an abutment nut 56 and washers 57, a hemispherical shell 61 being mou'nted for adjustment on the outstandin portion of the arm 36, between the was ers 57. globe 60, repI'e senting the moon, is mounted on the part 36, within the shell 61. The "globe 60 preferably is colored black, whereas the outer surface of the shell 61 is sil'vered or gilded, to

represent the illuminated portion of the surface of'the moon. On the outer end of the member sea nut 59 is threaded. the same coacting with a compression spring 58 to hold the shell 61 in any osition to which it may have been adjuste circumferentially of the outstanding portion of the angular arm'36.

On the shaft 33 is mounted'a hub 39, held in adiusted positions by a set "screw 40 (Figure 2) the hub carrying a spider supporting a ring dial 42, which is marked, as shown mostcllearly in Figure 4, with the numerals of the lunar and calendar months, as indicated at 43. It is with these markings at 43 that the index 37 of the arm 36 coacts, in a way and fora purpose which will be made manifest hereinafter. The earth globe 44 is carried by the shaft 33 and the shaft is located in the globe at an angle represented by the inclination of the axis of the earth with respect to the ecliptic. The earth globe 44 has a mark 45 which will be alluded to hereinafter.

outwardly of the earth globe 44, a sleeve 46 is mounted for rotary adjustment on the shaft 33. A compression spring 47 surrounds a portion of theshaft 33 and abuts against the sleeve 46 under the impulse of a wing nut 48 threaded on the shaft, the sleeve thus being held frictionally against the earth globe 44, for rotary adjustment, and to provide for the ad'ustment of a lanet locator which is carrie by the sleeve. he planet locator embodies a cross piece 49 mounted'in the sleeve and shown best in Figure 4. Pointers 50 areadjustable along the cross piece 49 and are adapted to cooperate with the markings 4-3 on the ring dial 42, the pointers being held in adjusted positions byrset screws 52. At its outer. end (Figure 2) the cross piece-49 has a head 52, wherein an extension rod 53, constituting part of the planet locator, is mounted for sliding adjustment longitiulinally of the cross piece, the extension rod being held in adjusted positions by a set screw 54 threaded into the head 52, ashers and spacers 55 are distributed along the shaft 33, to hold the members 35 and 39 against too fret rotation, the function of the spring 4-7 and the nut 48 in this connection being obvious when F igure 3 is noted.

In practical operation, the stop pin 76 is inserted into the opening 75 individual to the month marking 20 on the dial 19, for which the instrument is to be setor, if the month selected happens to be adjacent to the bottom of the dial ]9 or adjac'ent to the top thereof, it may not be necessary to use the stop pin, since the arm 18, being disposed in an approximately vertical position, will not swing after being once set. Assuming, however, that the stop pin 76 is used, the arm 18 is swung until the nuts 34 or the coupling 7 32 (Figure 3) abut against the stop pin. The earth globe44 thus is positioned properly for the selected month. The planet locator 4953 is swung until it is in alinement with the earth globe 44 and the sun globe 27. The arrn 36 is swung on the shaft 33 until the moon globe coincides with the planet locator 49-53; the earth globe 44, the sun globe 27 and the moon globe 60 being alined, (Figure 6), and the moon globe being located opposite or behind the earth globe from the sun globe, this being the relative positions of the elements spccified, when the moon is full; Now, from an almanac the operator ascertains the date in the particular month in which he is operating, on which the full moon occurs. The ring dial 42 then is rotated, until the full moon date. derived from the almanac, coincides with the appropriate one of the pointers 50 on the planet locator, the ring dial 42 thus being set for the month.

'Noting Figure 1, suppose that it is desired to set the instrument for a coniunctiou involving the earth. the moon and hlars. Then the conjunction date is obtained from an almanac and the planet locator .9 53 is swung until the appropriate one of the pointers 50 registers with the conjunction date onthedial 42. The planet locator is shown positioned thus in Figure 1. The arm 36 is swung to bring the moon globe 60 into alinement with the planet locator 49-53, and the proper arm 10 is swung to bring the globe 12, which represents the planet Mars, into alinement with the planet locator. By a similar operation, readily understood by those skilled in the art, other planetary conjunctions, whether inferior or superior, may be demonstrated, the rod 53 of the planet locator being slid outwardly on the cross piece 49 when necessary, in order to provide for a proper setting of these planets which are most remote from the sun.

As the moon globe 60'is adg'usted in an orbit about the earth, the shel 61 should be turned so that it always faces the sun. By doing this all of the moons peculiar changes and phases from new to full and back to new again will be clearly demonstrated. The earth globe 44 should always be positioned so that the mark 45 on the earth globe is uppermost, regardless of the position of the earth in its orbit. By observing this directiomthe arrival of the solstitial and equinoctial points will always come into proper alinement with the sun, at the time of these quarter-annual occurrences.

The shaft 5 preferably is keyed at 98 into the plates 4 on the standard 2, and the hub 25 which carries the dials 19 and 21 is keyed at 99 to the shaft 5 to prevent rotation of the dials with respect to the shaft, and to prevent a rotation of the shaft in the plates 4, the shaft having a longitudinal movement in the plates, when the spring 7 is compressed by the action of the nut 80. The disk 26 may be made of brass, or may be polished, and, being located behind the sun globe or member 27, emphasizes the luminosity of that body.
